Abstract:Based on the analysis of existing anti-sliding structure and the research status at home and abroad, according to the current main landslide anti-slide piles and prestressed anchor cable anti-slide pile structure of ordinary structure, this paper analyzes the anti -slide pile indoor and outdoor test, internal force calculation method, calculation method of pile spacing, pile method for determining the position and the anchoring depth re- search present situation. It discusses the circumference coupling anti-slide pile-soil and the structure of the new type arch string coupling anti-sliding research present situation and development trend in the future. Fur- thermore, the idea and method of post-evaluation of landslide prevention and control effect are put forward, and the popularization and application of new theory and technology of landslide prevention and control are empha- sized on the premise that the pile-soil coupling gives full play to the soil's own strength. A new type of anti- sliding structure with "zero displacement" control is put forward according to the requirements of controlling creep slip of high-speed railway roadbed.
